328i n52 e85 conversion?

BravoJohny33 · 03-10-2018, 08:16 PM

I know it wont do anything to increase the HP but e85 here is almost a dollar cheaper than premium fuel. If I do end up fixing the VCG I was thinking about replacing the injectors but I don't know what ones I would use for e85 and what fuel pump.

PS I don't care if the fuel ruins the engine in two years. The car isn't worth anything. But e85 should be 100% safe with injectors, pump and tune.

Sounds pretty pointless to me. E85 burns faster than regular gasoline so you're not truly saving $1 per gallon. Personally, I wouldn't mess with it

e85 is 20% less efficient and with a dollar spread I am saving at least 30 cents per gallon. Plus I get higher octane than 87.

Not true.

Also spending $1000+ to make your car E85 ready in order to save .30c/gal is fucking absurd.

If you are saving $.30/gallon and it costs $1k to convert you need to buy over 3,000 gallons before you break even. That’s like 200 tanks of gas, or about 4 years to break even at 1 tank per week.

And that’s at the same mileage which it’s not, supposed to be 20% worse mileage so add 20% more into the picture.

So in 5 years you will be dead even. Year 6 you will be ahead.

Not smart

“Pointless” “not smart” etc. There’s always stupid comments that don’t add any value.
I think its cool even if it doesn’t pick up significant power.
If you were to upgrade internals, it could definitely make good power over 93/91 octane.

Do you still have the car?
